While all spark plugs may look the same, they are not all created equal. The thread size is one thing that sets them apart. There are three types of threads: tapered, parallel, and rolled.
Each type has its own benefits and drawbacks. Tapered threads are the most common type used in spark plugs. They create a seal with the cylinder head and prevent oil from leaking into the combustion chamber.
Parallel threads are less likely to leak oil, but they require more torque to tighten properly. Rolled threads are the strongest type of thread, but they can be difficult to remove if they become seized in the cylinder head.
When it comes to spark plugs, there are different types that you can choose from. However, they all have the same thread size. This means that you can use any type of spark plug in your vehicle, as long as it has the same thread size.
Spark plugs are important because they help ignite the fuel in your engine. Without them, your engine would not be able to run. There are different types of spark plugs available on the market, and each one is designed for a specific type of engine.
If you’re not sure which type of spark plug is best for your vehicle, you can always consult with a mechanic or look up the information online. In most cases, the right type of spark plug will be listed in your owner’s manual.

Spark Plug Thread Size Chart
If you’re a car enthusiast, then you know how important it is to have the right spark plug for your engine. But with so many different types and sizes of spark plugs on the market, it can be hard to know which one is right for your car. That’s where a spark plug thread size chart comes in handy.
A spark plug thread size chart lists the different types and sizes of spark plugs that are available, as well as the specific thread size that each plug has. This information can be extremely helpful when choosing the right spark plug for your car.
